Sonography in differential diagnosis of deep venous thrombosis of the leg.

The lower extremities of 60 consecutive symptomatic patients were examined first by ultrasound (US) and then by phlebography. Deep venous thrombosis was found in 17 patients by means of venography. A hematoma was detected by US in six legs without thrombosis. A popliteal cyst was observed by US in five cases; one patient had a concurrent deep venous thrombosis. It was concluded that symptomatic patients with a negative phlebography should be examined by US for correct diagnosis and treatment, although US cannot replace phlebography.

Ultrasonography in carcinoma of the gallbladder.

Cholecystosonography in approximately 40,000 patients over five years in two university hospitals revealed 30 (75%) of the 40 macroscopic primary carcinomas. In 3 cases the carcinoma was obscured by gallstones with shadowing, in 3 cases the origin of a tumour mass was misinterpreted, and in 4 cases the neoplastic growth mimicked gallbladder inflammatory changes or sludge. Malignancy was incorrectly diagnosed or suggested in 25 patients. The most frequent cause of a false positive report was acute or chronic inflammation, found at surgery in 16 gallbladders. Four carcinomas of the pancreatic head were believed to be gallbladder tumours. Cirrhosis with marked gallbladder wall thickening, gastric carcinomas with metastases, a common duct carcinoma, and two cases of sludge (with normal control studies) caused a false suggestion of gallbladder carcinoma. The most frequent ultrasonographic finding in gallbladder carcinomas was a mass filling the gallbladder (15 diagnosed cases), followed by wall thickening (9 cases), and polypoid or fungating tumour (6 cases). Real-time ultrasonography is a useful method for the preoperative diagnosis of gallbladder carcinoma, but considerable diagnostic problems in the differentiation from inflammatory diseases may be encountered.

Aspiration biopsy of the spleen in patients with sarcoidosis.

Fine-needle aspiration biopsy of the spleen was performed on 101 patients with suggested sarcoidosis; it was the final diagnosis in 79. Adequate specimens were obtained in all cases with a 0.8 X 80 mm or 0.7 X 40 mm disposable needle. Fine-needle biopsy specimens of the spleen showed a granulomatous reaction in 19 out of the 79 cases with sarcoidosis (24%). There were three minor biopsy complications that required no treatment.

Ultrasonography in acute gallbladder perforation.

The files of patients with acute cholecystitis from two large university hospitals from the years 1978-1985 were employed to find the cases with acute gallbladder perforation for this study. Only those patients (n = 9) were selected for the analysis of sonographic signs of acute gallbladder perforation who had less than 48 hours of symptoms before sonography, and were operated upon within 24 hours of the sonography. Patients (n = 10) with non-complicated acute cholecystitis and identical in regard to the duration of the symptoms and the timing of the sonography and the operation formed a control group. The sonographic findings in patients with gallbladder perforation were pericholecystic fluid collections, free peritoneal fluid, disappearance of the gallbladder wall echoes, focal highly echogenic areas with acoustic shadows in the gallbladder, and an inhomogeneous, generally echo-poor gallbladder wall.
